Missing functionality - Notifications tab

I`m missing a notification tab where I can see all the notifications I have received to my emai, same that exist in any social network like facebook, google plus, etc.

Classic scenario:I wish to direct my workmate to a comment I made on an issue. Inside JIRA context its impossible to find the comment, unless I know where and which one it is.Also, if the user doesn't open his inbox, even if he stays all day long inside JIRA, he wouldn't be aware of the fact that his issues been commented, and are in progress.

Its extremely expensive.
2000USD for notifications is just too much to ask, and more than that we do pay for Jira, so why we need to pay $2000 for an elementary feature.
@jira support, @Jira Administrator - can you guys help with this item, pass it to the product guys? Does this feature exist in some roadmap?
Thank you :'( :'( :'(
